HFS+ does not recognize HFS disk, reinstall not working properly

Hi, lots of people seem to have same or similar problem, but I found no solution on this forum or elsewhere. So I submitted the following to paragon support - and hope this will help...):

HFS+ 9 build 9.0.3, W7/x64 home premium)

After first installation of HFS+ it did not recognize the external mac drive (USB). I found that HFSactivator was NOT running, and could not start it manually.

I then deinstalled HFS+, after reboot re-installed HFS( version 9.0.3 from fresh download).

First problem was a message "your trial lic has expired" but choosing "10 day trial version" worked OK.
After installation and reboot HFS activator was still not running, but manual start worked OK (had to repeat "choose 10 day trial version"!?). I then plugged in the USB disk but it is still not being recognized.
